In this major release, Mocha adds the ability to run tests in parallel. Better late than never! Please note the breaking changes detailed below.

Let's welcome @​giltayar and @​nicojs to the maintenance team!

💥 Breaking Changes

• #​4164: Mocha v8.0.0 now requires Node.js v10.0.0 or newer. Mocha no longer supports the Node.js v8.x line ("Carbon"), which entered End-of-Life at the end of 2019 (@​UlisesGascon)

• #​4175: Having been deprecated with a warning since v7.0.0, mocha.opts is no longer supported (@​juergba)

  ✨ WORKAROUND: Replace mocha.opts with a configuration file.

• #​4260: Remove enableTimeout() (this.enableTimeout()) from the context object (@​craigtaub)

  ✨ WORKAROUND: Replace usage of this.enableTimeout(false) in your tests with this.timeout(0).

• #​4315: The spec option no longer supports a comma-delimited list of files (@​juergba)

  ✨ WORKAROUND: Use an array instead (e.g., "spec": "foo.js,bar.js" becomes "spec": ["foo.js", "bar.js"]).

• #​4309: Drop support for Node.js v13.x line, which is now End-of-Life (@​juergba)

• #​4282: --forbid-only will throw an error even if exclusive tests are avoided via --grep or other means (@​arvidOtt)

• #​4223: The context object's skip() (this.skip()) in a "before all" (before()) hook will no longer execute subsequent sibling hooks, in addition to hooks in child suites (@​juergba)

• #​4178: Remove previously soft-deprecated APIs (@​wnghdcjfe):

  • Mocha.prototype.ignoreLeaks()
  • Mocha.prototype.useColors()
  • Mocha.prototype.useInlineDiffs()
  • Mocha.prototype.hideDiff()

🎉 Enhancements

• #​4245: Add ability to run tests in parallel for Node.js (see docs) (@​boneskull)

  ❗ See also #​4244; Root Hook Plugins (docs) -- root hooks must be defined via Root Hook Plugins to work in parallel mode

• #​4304: --require now works with ES modules (@​JacobLey)

• #​4299: In some circumstances, Mocha can run ES modules under Node.js v10 -- use at your own risk! (@​giltayar)

📖 Documentation

• #​4246: Add documentation for parallel mode and Root Hook plugins (@​boneskull)
